Abstract:
The light-emitting device includes a light-emitting element, a light-transmissive member, a light-blocking layer and a light-reflective member. The light-transmissive member has a first main surface and a second main surface opposite to each other. The first main surface and the second main surface are smaller than a light-emitting surface of the light-emitting element. The first main surface faces the light-emitting surface of the light-emitting element. The light-blocking layer is disposed on the light-emitting surface to cover a region between an outer edge of the light-emitting surface and an outer edge of the first main surface. The light-reflective member covers at least a portion of lateral surfaces of the light-emitting element and at least a portion of the light-transmissive member. The light-blocking layer extends inward of the outer edge of the first main surface.
